1. Introduction

10
For large amount of information or information which required to be reported semi-statically, MAC header
type of feedback is required.

In this contribution, we propose feedback polling IE.

Description/Notes
Feedback_Polling_IE
MCS level for transmit feedback header
Indicating the first Distributed LRU index for transmission
The allocation is valid for 2(d–1) superframe starting from the superframe
defined by allocation relevance. If d == 0b000, the prescheduled feedback
header transmission is released. If d == 0b111, the prescheduled feedback
header transmission shall be valid until the BS commands to release it.
Transmit feedback header every [2p superframe]
Downlink LRU indicating which RUs or which type of RU to work on for
feedback
0b000 : Whole bandwidth
0b001 : Subband CRUs in frequency partition 0
0b010 : Subband CRUs in power boosted frequency partitions
0b011 : Subband CRUs in non power boosted frequency partitions
0b100 : DRU/mini-band CRU in frequency partition 0
0b101 : DRU/mini-band CRU in power boosted frequency partitions
0b110 : DRU/mini-band CRU in non power boosted frequency partitions
0b111 : Whole bandwidth over whole carriers
See table y.
If Feedback type == 0b000 to 0b011, then N indicates how many PMI and
CQI for neighboring cell should be reported
If DLRU ≠ 0b111,
0b000: Primary carrier
0b001: Secondary carrier 1
0b010: Secondary carrier 2
0b011: Secondary carrier 3
0b100: Secondary carrier 4
0b101: Secondary carrier 5
0b110: Secondary carrier 6
0b111: Secondary carrier 7

Descriptions
ICT (interference coordination type) == 0b00
Downlink PMI restriction feedback, strongest
interfering PMI and CQI differences for
neighboring cell of ID, Temp_BSID. (Refer
15.3.11.1.1.1.) Temp_BSID is diversity set
member ID assigned to this BS.
ICT (interference coordination type) == 0b01
Downlink PMI recommendation feedback,
weakest interfering PMI and CQI differences
for neighboring cell of ID, Temp_BSID. (Refer
15.3.11.1.1.1.) Temp_BSID is diversity set
member ID assigned to this BS.
ICT (interference coordination type) == 0b10
Downlink Co-MIMO feedback, PMI and CQI
differences for neighboring cell of ID,
Temp_BSID.
(Refer
15.3.11.1.1.1.)
Temp_BSID is diversity set member ID
assigned to this BS.
ICT (interference coordination type) == 0b11
Downlink CL-MD feedback, PMI and CQI
differences for neighboring cell of ID,
Temp_BSID.
(Refer
15.3.11.1.1.1.)
Temp_BSID is diversity set member ID
assigned to this BS.
